'.O ALL WHOM IT MAY CONCERN:

Be it known that I, H; P. JONES, of Davenpd'rt, in the county of Scott,and State of Iowa, have invented a new and improved Machine for KneadingDough; and I do hereby declare that the following isa full, clear, andexact description thereof, reference being had to the accompanyingdrawings, making a part of this speci. flcation, in which- Figure 1 is aperspective view of the improved dough-kneader.

Figure 2 is a longitudinal section, taken centrally through the machine.

Figure 3 is a vertical transverse section through the same.

Similar letters of reference'indicate correspondingy parts in theseveral gures.

Thisvinvention relates to a new and improved machine, which is designedfor kneading dough, and which may also be successfully employed forwashing, salting, and working butter.

The invention consists in the use of a double-bevelled or taperingblade, having bevelled n'ds, in conjunction with a trough or box havingharing sides and ends, said blade being applied to its box in suchmanner that it receives when in operation arolling or travellingmovemcntbackand forth, from one end of the box to the other, therebypressing and cutting vthcA dough, `and `mixing it ima more perfectmanner than canA be done by corrugated rollers, which have .beenhitherto lemployed for this purpose, as will be hereinafter described.

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation.

' `In the accompanying drawings, A represents a rectangular oblongtrough or box, which is made with daring sides and ends, and withovcrhanging strips, a a, at its ends for the purpose of preventing theescape of any fluid substances from the box at these points. On theoutside of the longitudinal sides of the box A, and secured firmlythereto, are rack-plates, B B, the teeth of which project above theupper edges of said sides, as clearly shown in the drawings, so as toengage with the teethwhich are formrd on the gudgeons of the rotaryblade C. These rack-plates are made with shoulders, b I), for receivingunder them the sliding keepers c c, in which the gudgeons of the rotaryblade C havetheir bearings. 'The length of the racks B B may be slightlygreater than the length of trav-cl of the blade C, allowing a space atthe terminus of the rack for the lremoval of the blade C, whenrequired.This blade is constructed with tapering or bevelled edges, d d, andwith'its ends bevelled, as shown in iig. 1. The parallel edges of theblade are bcvellcd or made thin in order to prevent these" edges fromliability of carrying up the dough with them; being inclined orbevclled, as shown, the dough will not readilyl adhere to them andvbetossed up out of the box. The bevellcd ends of the blade C conform tothe inclined sides of the box A. When this blade is in theposition showniniig. 3, and as the blade approaches a horizon? tal position, thespaces between thc sides of the box and ends of the blade increase, thusallowing the material which is being worked tov let go ofthe blade. Witha square-cornered blade and a box with perpendicular sides, the materialwould be carried around with the' blade or thrown out of-the box, butwith a blade of the hexagonal shape shown, this will not be the case.The gudgeons g g are secured in a suitable mannar to the middle of theends of thebladc C, and arc-constructed with teeth upon them, whichengage with the teeth on the rackplates B, Yas shown. The ends of thegndgeons gg are passed through the sliding keepers c, so as to revolvefreely ;r yand on one end of one of the gudgeons, g, a crank-handlc issecured, by turning which the blade C will be caused to revolve, and atthe same time roll along upon the racks. When the blade C is in thismanner rolled to one ond of the box A, its motion is` reversed, and itis rolled back again. By the action ofthe blade C upon the dough orbutter 'putin box A, the substance is pressed into thin slices, lyingone upon another, and at every passage of the blade from one cnd to theother of thcbox, the slices are subdivided, pressed down, and mixed oneinto the other; thus every part of thc substance can be thoroughly andexpeditiously kneadcd.

'Haring described my invention, what I claim as new, and desire tosecure by` Letters Patent, is-

1. They einploymentof a traversing rotatingblad-e of a hexagonal form,in conjunction with abox, A, having ilai'ing-sides'and ends,Ysubstantially described and for the purposes set forth.

2. The construction of the blade C, with toothed gudgeons gg on itsends, in combination ,with the sliding keepers e c and shoulderedrack-'plates B B, substantially as and'fo: the purposes described. f
